Vice President Cheney called on Congress today to permanently extend the Protect America Act as the White House launched a drive to secure the tools it says are needed to fight a continuing terrorist threat beyond the law's Feb. 1 expiration.

In a speech to a sympathetic audience at the Heritage Foundation, a conservative Washington-based think tank, Cheney also said the law must include immunity from lawsuits for telecommunications companies that assisted the U.S. government's electronic surveillance efforts after Sept. 11, 2001.

"There is no sound reason to pass critical legislation like the Protect America Act and slap an expiration date on it," Cheney said. "The challenge to the country has not expired over the last six months. It won't expire any time soon, and we should not write laws that pretend otherwise."

The Heritage Foundation concerns itself with many issues, from missile defense to Europe to public administration, and about 20 other subject areas. It regularly publishes comprehensive articles, papers, journals, etc., expressing its strong neo-conservative opinions in these subject areas.
